Quantitative Analysis of the Open Access Citation Advantage

Abstract

　In order to promote open access by Japan’s institutional repositories, libraries have been asking researchers to provide articles. However, since its advantage is unclear, the success rate of the activity has been stagnant. Considering the situation, this study examined whether the advantage exists, focusing on citations. Although the number of open access articles by Japan’s institutional repositories is limited, a comparison of their citations with those of various types of open access articles did not confirm the advantage.
